Spatius's answer

Spatius combines photorealistic 3D Gaussian Splatting avatars with a cloud-edge rendering architecture built specifically for real-time AI interaction. Instead of rendering every frame on cloud GPUs and streaming it as video, Spatius sends lightweight motion data to the user’s device, where the avatar is rendered locally.

This approach addresses visual quality, network reliability, device coverage, and operating cost at the same time. It allows digital humans to remain responsive during long conversations, work across web, mobile, and intelligent hardware, and scale to high-concurrency production environments.

Phaserr's answer:

Most AI fitness tools write the program for you. Phaserr does the opposite: AI drafts a training block in seconds, and then the coach edits, reshapes and approves it. The software never publishes a program on its own — the coach stays the author, and the athlete's plan still carries their name and their thinking.

That one rule shapes everything else: every AI output lands in an editable block, not a locked plan.

Phaserr's answer:

Two reasons, depending on what you're leaving behind.

If you're coming from a spreadsheet: you get real structure — multi-week blocks, sets, reps, load schemes, progressions — and your athletes open the session on their phone instead of squinting at a shared sheet or a PDF.

If you're comparing against other coaching platforms: most of them either bury programming under billing and CRM features, or hand the programming over to AI entirely. Phaserr is built around the block builder, and the AI is a drafting assistant that you edit — not an autopilot. Free for individual coaches, AI included.

Spatius's answer

Spatius is built for companies and developers creating AI products that benefit from natural, face-to-face interaction. Its primary users include teams working in AI education, recruiting and interviews, customer service, smart terminals, digital assistants, intelligent devices, and AI companion products.

It is especially well suited to organizations that require long-duration conversations, high concurrency, cross-platform deployment, custom-branded characters, or reliable operation on constrained networks and hardware.

Phaserr's answer:

Independent strength and conditioning coaches and personal trainers who write their own programs — the ones currently running everything out of Google Sheets or Excel and sending PDFs.

Typically a solo coach or a small team with a handful to a few dozen athletes, who cares about how the block is structured and doesn't want a platform making training decisions for them. Not gyms looking for billing and membership software, and not athletes looking for a workout app.

Spatius's answer

Spatius was created to close the gap between digital human demonstrations and real-world deployment. Many avatar technologies can produce an impressive short demo, but become difficult or expensive to operate when conversations last longer, user numbers grow, or products must run across diverse devices and network environments.

The Spatius team developed its own cloud-edge 3DGS technology to solve these production challenges together. Today, Spatius helps companies turn AI into a more natural and expressive presence, bringing real-time digital humans into education, recruiting, smart devices, customer-facing terminals, and companion applications.

Phaserr's answer:

We're not coaches — that's the honest starting point. One of us is a designer, the other an engineer. We kept seeing the same thing: skilled coaches doing genuinely expert work, then losing hours to spreadsheet mechanics and PDF exports.

Because we're not coaches, we made a rule we won't break: the software never writes the program. It can draft, structure and speed things up, but the training decisions stay with the person who is qualified to make them. Phaserr is being built in the open with the coaches who use it — we ship, we listen, we fix.

Spatius's answer

Spatius is primarily built on proprietary 3D Gaussian Splatting technology and a cloud-edge rendering architecture.

Its cloud-based Motion Server converts generated speech into lightweight facial and motion data, while the AvatarKit SDK renders and animates the 3DGS character locally on the client device. Platform technologies include WebGL and WebGPU for web applications, Metal for iOS, and Vulkan for Android. Spatius can receive real-time audio through technologies such as WebSocket, WebRTC, LiveKit, and Agora, and can integrate with third-party ASR, LLM, and TTS providers.
